Be part of a forward-thinking team driving digital manufacturing transformation. In this role, you’ll:

• Bridge the gap between IT and OT with high-impact technical leadership
• Build secure, resilient industrial networks that enable Industry 4.0
• Shape OT standards, architecture, and cybersecure design practices
• Make a tangible impact on uptime, safety, and connectivity across plants

RESPONSIBILITIES

• Design, configure, and deploy OT wired/wireless network infrastructure in production environments
• Maintain and optimize industrial network performance, uptime, and security
• Lead Tier 3 troubleshooting and root cause analysis of OT network incidents
• Contribute to network architecture decisions, standards, and design blueprints
• Partner with engineering teams to integrate ICS, SCADA, IIoT, and smart devices
• Implement and manage network segmentation/zoning aligned to the Purdue Model
• Align OT security with corporate policies and frameworks (ISA/IEC 62443, NIST)
• Manage and patch OT networking hardware (Cisco IE switches, firewalls, routers)
